To enable others skilled in the art to make and use my machine I will proceed to describe its construction and operation. I construct my machine of cast and wrought iron (though the frame could be of wood). The frame lV IV WV I make strong and substantial, according to the scale of the drawings, which is one inch to the foot. I have a main shaft (Plate III, Fig. l, A1 A1) across the machine with two journals y y snugly fitted to boxes and well secured; on this shaft I firmly secure two cams; one E a full stroke, the other D a cut off cam; also the revolving levers F F F very strong, and of the length that I wish to raise the lifting gate (seen in Fig. 6) -and I also supply cog wheels or cranks to attach horse or steam power.

I construct a frame A A A A Fig. 4l for the full stroke cam E to which is firmly secured the mold plates B3 B3 B3 B3 Fig. 4

which in this figure represents the thickness of the brick I wish to make; the molds which are made true and smooth and a little larger at the bottom, being within these plates. At the same time the plates serve as slides to steady the cam frame. On each side of the cam frames and directly under each pounder I construct a solid foundation of wood or iron the upper surface of which constitutes the bottom o-f the mold and rests on the sills of the frame. View of said foundation detached seen at F in Fig. 9. The pounder comes down upon mold plate B3 which rests upon foundation. I construct above each of' tally in under the pounders. The square space f C, Pl. III Fig. 9 in these receivers are of the same size as the molds below them, and the inside of the receivers are flush with the inside of the molds; I make the inside of the hoppers a little longer than the receivers in their horizont-al diameterhaving their bottoms on the same level and five inches above the mold plates.

Immediately under the hoppers in a recess, I construct what I call a plunger.

The plunger D Fig. 10 is intended to force the brick when molded, out of the mold upon the carrying bnd K, K, which is beneath it. It is worked bymeans of lever C which in turn is moved by lever E represented in Fig. 3 and this is moved by the cam frame A, A, represented in the same figure.

The lower end of the hoppers as well as the back part of the receivers fits snugly down to the mold plates, so as not to bind them, as they have to slide out and in to receive their charge. In the front of the hopper I make an opening the whole width of the hopper inside and level with the bottom; in this opening slides in and out what I call the horizontal feeding gage, which will give any quantity of material desired, by making the gage thicker or thinner.

I make the opening between the hoppers and the receivers, through which the horizontal feeding gages force the clay, a little larger than the gages, in order that a sucient quantity of clay may be forced in at each movement of the gage.

In Fig. 3 the structure C, F, represents, in i i the upper part a view of one side of the covering of the receiver while the lower portion represents what has been described as the foundation. The first is hollow While object of which is to work the leversE, E,

by which the levers at the ends t strike against levers C C (one of which is seen detached in Fig. 10) at the part w and raises it into the position represented by the dotted lines, which movement depresses the plunger D down into the mold and forces the brick ready molded through onto the carrying or offbearing band.

rIhe lifting gate see Fig. 6 Plate III, is intended to work the pounders, the horizontal, and perpendicular feeding gages, I make it with slides and jaws, or slides only to guide and steady it, having a projection e: e: on one side of the gate of the thickness equal to the width of the blades of revolving levers, F, against which projection the revolving levers catch and carry up the gate. The gate has a head B with openings m, m,

in it, for levers C C which extend to each endof the machine frame, where I have rock shafts D2 D2 Fig. l2 with arms H, I-I, Pl. II, extending at right angles, with levers CA C and connected to and working horizontal feeding gages B5 B5, as seen in Plate II. The vertical feeding gages are attached to and move with the pounders and are described. The pounders I make with a shoulder a: Pl. III, Fig's. 15 and 16 to protect the mold plates. Above this shoulder the pounder is hollow, so that weight can be added or diminished, to suit the' material operated upon. To the pounders are attached arms B B Pl. II, extending to the head of the lifting gate, but not attached to it eXcept that the gate rises to them and carries them up; also attached to these pounders are what I call perpendicular feeding gages D, D, coming down inside of the hoppers. I also attach springs (Fig. 14 underneath) the guide frame which give additional impetus to the pounders. The bands K, K, Pl. II that run over the table, the rollers N, N, that carry them, I connect to main shaft A" A with bands or cogs.

Operation-In making bricks with my machine I prepare the clay in the ordinary way that clay is usually prepared by grinding it, or otherwise making it in a proper state for molding, with this difference-that I only make it damp-sutiicient to adhere. The clay is then thrown into the hoppers,

when the horizontal feeding gages furnish a constant and regular supply to the molds, and receive at the same time aid from the perpendicular ones. The horizontal gages at regular periods or when pushed in form the bottom of the hoppers, and when drawn out expose .or leave a cavity which the perpendicular ones immediately fill and so on with great harmony of action, during the operation of the machine.

The object of cam E as represented in Fig. 4 is to move the mold plates B3 &c. in Figs. 4 and 5 so as to receive and deliver the brick. And by the alternate reciprocating motion of the mold plates moved by the cam E at each time an end of a mold plate is protruded a brick is delivered upon the oft'- bearing band at the same end of the machine. The motions are so arranged that while the mold at one end is delivering a brick, that lat the other end is being filled. When the molds are filled solid by the concussion from the blows of the pounders, the mold plates are moved by the action of the full stroke cam E, Fig. 4, so that the brick comes directly under the face of the plunger, the motion of which has been described and in direct contact with the face of the brick, while the action of the cut off cam D, which works the levers connected with the plungers,kforces the brick through the mold on to the off bearing band K, K, which carry the brick to any distance required without stopping the machine.

What I claim is- 1. The combination of the perpendicular feeding gage with the pounder in the manner described; and in combination therewith the horizontal gage working in the bottom of the hopper.

2. I also claim the arrangement of the cam and lever, operating the plunger as d escribed; and in combination therewith the arrangement of the cam which operates the mold plate.
